Idle time out message

[Janardhanan, Ajith (AJANARDH)]

When the idle time out is reached, in stead of the standard "421 Service
not available, remote server has closed connection" message spitted on
to the client, I need to display a different message. Greately
appreciate if any one could tell me how to do it. 

Currently my customized messages are in the FtpStatus.properties file,
which is in the org.apache.ftpserver.message package. Looks like the
above message is not pulled from this file.

I am using the code from the 1.4 branch.
